Indoor space subdivision for indoor navigation
Proceedings of the Sixth ACM SIGSPATIAL International Workshop on Indoor Spatial Awareness - ISA '14, 2014There are a number of great attempts to develop an indoor navigation that provide the most optimal path and guidance. Finding a way in large buildings can be a challenging task. In order to represent the real situation to a maximum extent, a representation of the whole room as one single indivisible object is not enough as such representation is very ...

Multi-Polarized Channel Statistics for Outdoor-to-Indoor and Indoor-to-Indoor Channels
2010 IEEE 71st Vehicular Technology Conference, 2010Compared to classical spatial MIMO wireless systems, cross-polarized MIMO systems are an interesting way to reduce equipment size while reducing the inter-antenna correlation. Cross-Polar Discrimination (XPD) and Co-Polar Ratio (CPR) are two important parameters describing multi-polarized channels.

Indoor sign Detection System for Indoor Assistance Navigation
2021 18th International Multi-Conference on Systems, Signals & Devices (SSD), 2021Indoor signage plays an important role in finding specific destinations and way-finding especially for blind and visually impaired people (VIP). In this paper, we developed a new indoor signage classifier using deep convolutional neural Network (DCNN).

2016 IEEE 32nd International Conference on Data Engineering (ICDE), 2016
A large part of modern life is lived indoors such as in homes, offices, shopping malls, universities, libraries and airports. However, almost all of the existing location-based services (LBS) have been designed only for outdoor space. This is mainly because the global positioning system (GPS) and other positioning technologies cannot accurately ...

In industrialized countries most of the time is spent indoors. The basic ambient parameters for a thermally comfortable indoor climate are air temperature, air velocity, humidity and radiation pattern. Besides the thermal component, the concentrations of air pollutants in the indoor air are also of importance for wellbeing and health.

Indoor-indoor and indoor-outdoor propagation trial results at 2.6 GHz
2012 Loughborough Antennas & Propagation Conference (LAPC), 2012This paper presents delay spread, coherence bandwidth, and angle-of-arrival statistics derived from an extensive MIMO channel measurement campaign carried out at a central frequency of 2.6GHz. The measurement scenarios include indoor-indoor, indoor-outdoor and indoor-outdoor-indoor.

Location prediction enables us to use a person's mobility history to realize various applications such as efficient temperature control, opportunistic meeting support, and automated receptionists. Indoor location prediction is a challenging problem, particularly due to a high density of possible locations and short transition distances between these ...

Penetration Loss at 60 GHz for Indoor-to-Indoor and Outdoor-to-Indoor Mobile Scenarios
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020This paper investigates the penetration loss of an office building in indoor-to-indoor (I2I) and outdoor-to-indoor (O2I) mobile scenarios. The measurements were collected using our 60 GHz double-directional switched-antenna channel sounder. During measurements, the transmitter, mounted on a tripod, was placed in an office and outside of the building ...

Analysis of indoor-indoor and satellite/HAP indoor propagation effects
11th International Conference on Antennas and Propagation (ICAP 2001), 2001Satellite and high altitude platforms (HAPs) are an important concept for next generation fixed and mobile communications. To predict indoor field strength levels from such distant transmitters, modifications to the standard indoor ray-tracing concept are proposed.

Mass-market requirements for indoor positioning and indoor navigation
2010 International Conference on Indoor Positioning and Indoor Navigation, 2010The next step in location services will be repeating the success of location services in outdoor use for navigation and local search in the indoor environment. In order to make indoor positioning and navigation reality in large scale not only compelling business opportunities must be present, but also the technology must be low-cost, low-power, have ...
